Claims. 1

This invention relates to an improvement in concrete construction forms and more particu larly has reference to a novel arrangement of simple standardized structural elements capable of assembly into casings of a variety of sizes and shapes.

The primary object of this invention is the provision of a series of interchangeable structural forms for concrete work and the like which are adapted to a variety of sizes and shapes.

An important object of the inventionis the provision of a concrete form which is made of simple, sturdy and inexpensive elements.

An additional important object of the invention is the provision of a concrete construction form which is specifically adapted for quick and easy assembly with a minimum of tools and labor.

An additional object of this invention is the provision of a structural form in which novel and highly effective reinforcing and anchoring means are employed.

A further important object of the invention is the development of adjusting means for bracing,

anchoring and positioning structural forms for construction work.

These and other important objects of the invention to be later apparent as this description proceeds, are attained in the invention, one embodiment of which has been illustrated in the accompanying drawings, wherein:

Figure 1 is an elevational view, partly in section, and a brace forming a part of my invention;

Figure 2 is a horizontal top plan View of a form constituting a part of my invention;

Figure 3 is an end view of Figure 1;

Figure 4 is a perspective view of a detail of Figure 1;

Figure 5 is a perspective view of the construction form, shown in Figure 1;

Figure 6 is an end elevation of another brace element illustrating a principal of the invention;

Figure '7 is a top plan of a corner construction form;

Figure 8 is a perspective of a part of the corner form in Figure '7;

Figure 9 is a perspective of another part of the corner form of Figure 7;

Figure 10 is an end elevation of a gable form.

Referring now in detail to Figures 1 through 4, there is seen a construction form Ill, anchored and supported in predetermined position by a brace indicated generally at l2. As one example of its use, the form it is positioned upon a footing l4 provided with the usual reinforcing rods l6 extending therefrom and into the form for reby means of threads and inforcing a concrete construction to be erected on said footing.

The form In, comprising a part of my invention, consists of a series of identical sheet metal panels or plates I8, each having an inner surface of plane shape, while an out turned peripheral flange and rib reinforcing means 22 are provided upon the outer surface. Spaced apertures 24 in the flanges 20 form means for detachably fastening the panels in desired relation to each other. Strap means 26 retain the panels I8 in the desired spaced relation to constitute a form or casing while an apertured plate 28 is secured upon the straps 26, whereby reinforcing rods 30 may be supported as a preliminary to being anchored in the concrete when the latter has hardened.

A bracing means, indicated generally at I2, is employed to position and reinforce the construction form during use. The brace consists ofa pair of laterally spaced standards 32 of generally triangular configuration, secured to base members 34 and supporting at their upper ends a transverse beam 36, suitably reinforced by struts 38. The beam 36 is longitudinally slotted as at 40 for the reception of a plurality of supporting rods 42, the latter engaging the straps 26 and being longitudinally slidable and vertically adjustable in said slot 40, vertical adjustment being effected nuts, indicated at 44. Each standard includes a vertical member, slotted as at 46, which slidably receives therein a rod 48, provided with screw threads and nuts for. lateral adjustment relative to the standard. At its inner end each rod 48 is pivotally connected to a pair of links 52 whose other extremities adjustably engage the flanges 20 of the form. Suitable anchoring means 54 secure the base 34 to the ground.

From the foregoing description, the method of operation of the form and brace will be readily apparent. The casing It is assembled to any desired dimension to provide a construction for footings, foundation walls and the like, the transverse beam 36 and rods 42 permitting adjustment of the form to any desired height. The top plate 28, not only constitutes a closure where desired but provides means for adiustably positioning reinforcement 16 and rods 30 or other anchoring means disposed in the form. The lateral rods 48 and their associated links constitute convenient means for reinforcing the sides of the form at any desired point and the members 54 serve to facilitate securing of the base 34' in position.

It will therefore be evident that this form constitutes a casing means which may be expeditiously assembled into a variety of forms, and to which additional units may be fully added as the construction work progresses.

When a wall or other structure is built up by a series of layers 56, 58 (Figure 6) each poured and hardened in its turn, I may alternatively or in conjunction with the brace means heretofore disclosed, employ a cross reinforcement consisting of a plurality of. straps 60. pivotally secured to the form l and having a series of apertures 62 for selective engagement by the inturned end or hook of the rod 64, Whose opposite extremities screw threadedly engage the turnbuckles'lifi, see

cured to the anchors 68 which may conveniently comprise the reinforcing pins 30 mentioned hereinbefore. By the foregoing the wall 'forms are rigidly interbraced with each other and the foundation by an adjustable reinforcing means.

In Figures 7, 8 and 9, I show a set of form members which maybe employed in the. foregoing apparatus for the production: of corners. A pair ofsheet metal members 10 welded or otherwise secured together inzthe form of a right angle and reinforced by atruss 72', form the inner corner form, while the outer corner form 14 consists of two plates-secured. at right. angles to. each other. As will'be' understood, thecorner forms are intended to be: detachably. secured to the wall forms I0, spacing straps 26 being em.- ployed at suitable intervals.

In. Figure 1.0, is disclosed. a. form. for agable consisting of individual corresponding: right and left sections 7.6, 18; and: 80. Members in pairs of right and left units may be added or removed from the. center to vary the dimensions of the gable end.

Although I have described the invention as applied to concrete construction, it will be read.- ily understood that it. isequally useful with other materials. requiring. a casing or form to support the same; It will be. further understood that the forms. of my invention are preferably those of standard structural steel. elements: as plates, girders, channellmembers, bars, straps, rods. and the like.

I claimas my invention:

1. A construction; form comprising a supporting frame having side standards. anda horizon tally extending support beamv therebetween, a plurality. or formed pane-ls positioned between said standards, means; for adjusting said panels vertically. and horizontally reiativetosaid frame and for supporting said panels upon said beam, and brace means for adjustably reinforcing said panels, said brace means including apertured flanges carried by said panels, bars having pivoted links at one end thereof for attachment to selected apertures in said flanges and means for adjustably supporting the other end of said bars on said standards.

2. The combination of claim 1, wherein said last-named means includes vertically extending bars carried by said standards having elongated vertical slots, said first-named bars being threaded at said other end and extending through said slots, and a nut receivable on the threaded end or said first-named bars.

3. The combination of claim 1, wherein said first-named means includes spacer bars carried by said panels, rods having threaded ends extending upwardly from said spacer bars, an elongated horizontal slot in said beam receiving the threaded ends of said rods, and nuts, received on the threadedends of said rods adapted to engage said beam.

4. The combination; of claim .3; wherein said last-named: means includes vertically extending bars carried by said standards having elongated verticalslotssaid first-named bars-being threaded at said other end and extending throu h the slots, and a nut receivable on the threaded end of said first named bars;

5. The combination of claim 4-,. and a support p a arri by said spacer bars. and, adapted to selectively. position reinforcing rods for embedding in the construction, form...
